The secondary electrolyte material is selected to have a potential stability window sufficient to prevent degradation of the primary electrolyte, which prevents chemical reactions that cause the formation of ionic non-conductive materials on the surface of the electrode of the electrochemical cell. The cell is made by placing a multilayer electrolyte material between the positive and negative electrodes.
